Coolant hoses OK but found this

[Firewrench]

Checked the coolant hoses from engine to DEF unit, all OK. Big thanks to Rustynuts for the drawings. While I was under there, I found this harness pinched between the frame and a cast iron bracket that holds up the front of the DOC(cat). All these wires go to the sensors and electronics on top of the DOC. There was maybe a 1/4" gap, I have no doubt that this would have been a problem in the future. Loosened a few bolts and the inlet clamp and the straps holding the DOC up so I could get a little movement, then moved the harness to where it should be.
I wonder if/how many others are like this?

Nice catch, I’ll have to check mine. Another thing to check is the rear hydraulic lines to the levelers, mine and several others have found them tight across a frame rail and fuel tank. I added zip loom over them.

Thanks, now I have something to do tomorrow…
